What I claim is 1. A metallic packing comprising astuffing box adaptedto slidingly receive a piston rod, metallic sectional packing ringssurrounding said piston rod, lubricating material embeddedin andextending through said packing rings, a split ring =-surrounding saidsectional rings, the sides of the split ring and sectional rings beingconical, a ring on each side of said split ring and packing ringsconforming to the conical surfaces of said inner rings and terminatingat the split ring, a shell within said stuff ing box and having a flangeat its inner end loosely surrounding the piston rod, a coil springsurrounding the piston rod one end of which abuts against the flange ofthe shell and its other end'engages the inner surrounding ring. A

2. A metallic packing comprising a stuffing box adapted to slidinglyreceive a piston rod, metallic sectional packing rings surrounding saidpiston rod', a split ring surrounding said sectional rings, the sides ofthe split ring and sectional rings bfeing conical, means for lockingsaid rings against movement on each other, a ring on each side of saidsplit ring and packing rings conforming to the conical surfaces of saidinner rings and terminatin at the split ring, a shell within said stu ngbox and having a flange at its inner end loosely surroundlng the pistonrod, a coil spring surrounding the piston rod one end of which abutsagainst the flange of the shell and its other end engages the innersurrounding ring.

In testimon whereof I afiix my signature in presence 0 two witnesses.
